Abstract: A two-stroke engine includes a crankcase defining a cylinder bore, a piston moveably disposed within the cylinder bore, and a cylinder head that covers the cylinder bore. A wall surface of the cylinder bore, a piston combustion surface of the piston, and a head combustion surface of the cylinder head, cooperate to define a combustion chamber for combusting a fuel therein. A thermal conductivity reducing mechanism is disposed in thermal connectivity with at least one of the crankcase, the piston, and the cylinder head for reducing heat transfer from combusted fuel within the combustion chamber to at least one of the crankcase, the piston, and the cylinder head. The thermal conductivity reducing mechanism may include a layer of low conductivity material coating one of the surfaces defining the combustion chamber, or a void in the cylinder head and/or the crankcase adjacent the combustion chamber.

Abstract: An insulated exhaust port liner of a cylinder head assembly for fluidly connecting to an internal combustion engine of a motor vehicle includes a sealing layer. The sealing layer has a first surface defining a passage for fluidly connecting to the internal combustion engine and receiving exhaust gas. The sealing layer further includes a second surface opposite to the first surface. The liner further includes a thermal barrier layer coated onto the second surface of the sealing layer. The thermal barrier layer is a porous non-woven material for supporting the sealing layer on the cylinder head and reducing a transfer of heat from the sealing layer to the cylinder head.
